This photograph illustrates the technique for an ulnar motor nerve conduction study, recording from the abductor digiti minimi (ADM) muscle. The recording electrode (black, G1) is placed over the belly of the ADM. The reference electrode (red, G2) is placed at the proximal phalanx of the little finger. In this photograph, stimulation is being performed in the axilla. The patient’s arm should remain in a flexed position at the elbow when performing ulnar motor nerve stimulations.
